[Fedora-suds-list] authentication error

[Erik Myllymaki]

Hello,

Hoping for some help from the list - I am new to suds and SOAP in general.

The support team for the .NET service i am trying to access has told me 
that since i can successfully access their service using soapui, then 
the error I am having trying to access it with suds is on me to figure out.

The message sent to the service that works from soapui looks like:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" 
xmlns:ser="http://www.somedomain.com/Remote/services">
    <soap:Header>
       <ser:AuthenticationSoapHeader>
          <!--Optional:-->
          <ser:Username>myusername</ser:Username>
          <!--Optional:-->
          <ser:Password>mypassword</ser:Password>
       </ser:AuthenticationSoapHeader>
    </soap:Header>
    <soap:Body>
       <ser:GetMyProfiles>
          <ser:clientGuid>my-unique-guid</ser:clientGuid>
       </ser:GetMyProfiles>
    </soap:Body>
</soap:Envelope>

I am setting up authentication correctly, I think:

wsdl='https://www.somedomain.com/Remote/services.asmx?WSDL'
user = 'myusername'
pass = 'mypassword'
guid = 'my-unique-guid' # unique client ID code

client = Client(wsdl,username=user,password=pass)

printing client shows the one method that is exposed, as expected:

Suds ( https://fedorahosted.org/suds/ )  version: 0.4 GA  build: 
R699-20100913

Service ( ContentService ) tns="http://www.somedomain.com/Remote/services"
    Prefixes (2)
       ns0 = "http://microsoft.com/wsdl/types/"
       ns1 = "http://www.somedomain.com/Remote/services"
    Ports (2):
       (ContentServiceSoap)
          Methods (1):
             GetMyProfiles(ns0:guid clientGuid, )
          Types (2):
	    MyStuff	
             ns0:guid
       (ContentServiceSoap12)
          Methods (1):
             GetMyProfiles(ns0:guid clientGuid, )
          Types (2):
	    MyStuff	
             ns0:guid


When I try and access that method though:

     result = client.service.GetMyProfiles(guid)

I get an error.

(MyProfileResult){
    MyStuff = ""
    ErrorReturned = True
    ErrorMessage = "Error processing profile0: Object reference not set 
to an instance of an object.:System.NullReferenceException: Object 
reference not set to an instance of an object.
    at <path to coode>:line 71"
  }

When I turn on debugging, I see that the message does not have the 
Authentication credentials in the header like the request that does work 
in soapui:

The guid is working - if I mistype it I get an guid error. I am thinking 
maybe the auth mechanisms do not match u in some way...
Any advice greatly appreciated.
